运行此代码时，进行修正显示在标签上选择的第一个按钮的名称中的“功能radioButtonClick”，但是当你选择别的东西后，它不更新，并且按钮标签出来交换。

所以基本上，会发生什么情况是：

点击单选按钮，1 - >显示 “1选择” 然后， 点击单选按钮2 - >什么也没有发生。 然后再次点击 单选按钮，1 - >显示“2选择” 最后，再次 点击单选按钮2 - >显示“1选择”

我该如何解决这个问题？

预先感谢您。

您的代码没有什么意义，每次单选按钮更改时都会创建一个新标签，并且您在每次单击时注册一个新的NSD_OnChange事件处理函数，并且此处理函数会尝试在该函数的顶部创建另一个页面旧的，这是完全不受支持的行为！

有很多方法来编写，这里有3个例子：

!include "nsDialogs.nsh" 
!include "LogicLib.nsh" 

Page Custom radioButtonExamplePageMethod1 
Page Custom radioButtonExamplePageMethod2 
Page Custom radioButtonExamplePageMethod3 
Page instfiles 

var Group1Radio1 
var Group1Radio2

var label 

Function radioButtonExamplePageMethod1 
nsDialogs::Create 1018 
Pop $dialog 
${NSD_CreateLabel} 0 0 100% 6% "Please choose" 
Pop $0 ; Don't care about this handle 
${NSD_CreateRadioButton} 0 12% 40% 6% "1" 
Pop $Group1Radio1 
${NSD_OnClick} $Group1Radio1 radioButtonClicked_Method1 
${NSD_CreateRadioButton} 0 20% 40% 6% "2" 
Pop $Group1Radio2 
${NSD_OnClick} $Group1Radio2 radioButtonClicked_Method1 
${NSD_CreateLabel} 0 40% 40% 6% "" 
Pop $label 
; You could do 
; SendMessage $Group1Radio1 ${BM_CLICK} 0 0 
; here to simulate a click for the inital radio button state 
nsDialogs::Show 
FunctionEnd 

Function radioButtonClicked_Method1 
Pop $hwnd
